Resumen

Recent preliminary data have suggested that microbe-to-plant signals, and plant internal signals elicited by microbial signals, affect aspects of plant physiology, development and growth. The reported research investigated the responses of plants to signal compounds of microbial and plant origin, such as lipo-chitooligosaccharides (LCOs - signal molecules in rhizobia-legume associations), chitin and chitosan (present in fungal cell walls), and phenolic compounds (salicylic acid, acetylsalicylic acid and gentisic acid - internal signals in plants, often affected by signals from microbes)

Resumen

Salad tomatoes represent an important vegetable crop within Australia. However, the costs of both materials and labour involved in providing this crop with artificial support, in the form of trellising or staking, is high. This project examined the feasibility of using the plant growth regulator, paclobutrazol, as an aid to crop grown without trellising or staking under coastal conditions. Initially a rate of 4 mg plant-, applied as a soil drench 1, 15, 29, 47 or 57 days after transplanting were compared with non-treated plants under glasshouse conditions.

Resumen

Responses of rice to plant growth regulators on germination and seedling growth under NaCl salinity were studied to identify possible means of increasing salinity tolerance. Gibberellic acid (GA) promoted germination processes and a-amylase activity and increased plumule but reduced radicle growth after emergence. GA partitioned more metabolites towards the plumule than the radicle. Chlormequat (CCC) showed no beneficial effects and abscisic acid (ABA) inhibited germination under saline conditions. Overall there was no large difference in the performance of three rice varieties, BR29, IR8 and

Resumen

A knowledge of the allometry of algal growth and respiration can be applied to biomass-size distribution models which are in turn used in the prediction of fish yield and ecosystem studies. However, the scaling exponents reported in the literature are variable. This variation may be attributed to differences in the expression of cell size and phylogeny, but could also reflect small sample size which underlie most published regressions. This thesis establishes the allometry of algal growth and respiration based on a larger sample taken from the literature, and evaluates the effects of differenc

Physiologic responses to Gibberellic Acid (GA), I-Naphthalene Acetic Acid (NAA), Benzylaminopurine (BAP), and Abscisic Acid (ABA). suggest that Oosterium monilfferum has the ability to utilize these plant growth factors. The growth promoters NAA and GA both increased growth when added to the media. The cell division regulator BAP (a synthetic cytokinin). also had a promotive effect on growth. Abscisic acid was found to be inhibitive to growth.

Resumen

Abandoned agricultural lands in the Intermountain West are plagued by dense, persistent non-native vegetation. Targeted restoration tools are required to remove the competitive advantage of these non-natives while also removing the soil legacies they leave behind. Activated carbon (AC) is one such tool, with the ability to disrupt the mechanisms of allelopathy, positive plant-soil feedbacks, and altered nutrient cycling commonly used by non-native species. Previous studies have shown the success of high concentrations of AC in native plant community restoration on a small scale. Here, our goal

Resumen

Plant growth promoting rhizobacteria (PGPR) are those bacteria that colonise the rhizosphere of various plants and promote growth either directly by improving nutrient uptake by the plant roots or indirectly through the control of pathogens. Due to the negative effects associated with the prolonged use of chemical fertilizers and fungicides, a lot of emphasis is now being given to research that investigates an alternative, sustainable and environmentally friendly method of crop production and protection.

Resumen

We have studied the effects of exogenous salt on whole plant and suspension culture cells of the halophytic tomato Lycopersicon pennellii. Under low salt conditions (2.9 dS/M) plants showed enhanced (halophytic) growth (107% of control). At moderate (7.5 dS/M) and high (18.5 dS/M) salt levels, salt stress reduced growth to about 78% and 40% of control respectively. Salt-induced changes in root mRNAs were analyzed via two-dimensional PAGE of cell free translation (CFT) products. We have identified 14 proteins whose levels were enhanced by exogenous salt. One of these proteins was unique to low

Wastewater or fish effluent (FE) from freshwater aquaculture can be a good and cheap liquid fertiliser for plants. However, while it represents a good source of nutrients to support plant growth in a system called aquaponics, it appears that its use needs to be optimised to take full advantage of the potential benefits. Apart from mineral amendments, the use of beneficial microorganisms that can have a direct impact on plant growth and nutrient utilisation could be a promising option.

Plants have been observed to show a range of plastic responses to environmental conditions. For example, the abundance and distribution of nutrients, as well as the presence and proximity of local competition, have been seen to result in changes in root proliferation and architecture. However, whilst some species have been witnessed displaying certain responses under given circumstances, experimental evidence suggests that responses to environmental factors can be far from simple, and sometimes counter-intuitive.

This study augments these guidelines by investigating the diversity differences between second-growth and old-growth forests in relation to site quality.
